on the V3 BDA/MU and RU devices. The installer/operator can refer to this sticker to verify proper wire
connections.
Connect to BBU V3
Power ON: Turn on DC switch to D C IN
Power OFF: Turn DC switch to BATT CHRG, t hen
switch off DC from BBU V2 or other DC source
*Turn OFF all switches before connection (switch to AC OFF and BATT CHR G)
Turning ON the system with AC and ba ttery installed:
1. Turn on AC Breaker in the BBU V3
2. Turn on the battery breaker in the BBU V3,
3. If battery LED is not lighted up, press the RESET button for <5s, r elease when LEDs starts blinking
4. Turn on AC Switch in the BDA V3
Turn On the system with AC only :
1. Turn on AC Breaker in the BBU V3
2. Turn on AC Switch in the BDA V3
Turn ON the system with battery only (when there is no AC):
1. Turn on the battery breaker in the BBU V3,
2. If battery LED is not lighted up, press t he RESET button for <5s, releas e when LEDs starts blinking
3. Turn on DC switch once (to DC IN th en to BATT CHRG) to turn up the system by batter y only
4. DC switch should stay on BATT CHRG side afterwards at all other times
Run on Battery:
1. Turn off AC switch i n t he BBU V3 or BDA V3
Turn OFF the system:
1. Turn off AC switch i n t he BBU V3 and BDA V3
2. Turn off the battery breaker

Powering other devices:
There are 2 x 28VDC (when there is no
need for AP or FOU) and 1 x 48VDC
available for external devices.
Total Power Consumption including
BDA (100W max)/FOU (25W
max)/AP (3W) and all external
devices should be less than 205W.
All negative terminals from 48VDC
and 28VDC are tied to the ground.
Use only for +48V/+28VDC or
floating DC input devices. V3 DOES
NOT support -48V/-28VDC systems.
